Fixed a regression that prevented editable GenericRelation subclasses
from working in ModelForms (#21428).

Added missing to_python method for ModelMultipleChoiceField which
is required in Django 1.6 to properly detect changes from initial values
(#21568).

Fixed django.contrib.humanize translations where the unicode sequence
for the non-breaking space was returned verbatim (#21415).

Fixed loaddata error when fixture file name contained any dots
not related to file extensions (#21457) or when fixture path was relative
but located in a subdirectory (#21551).

Fixed display of inline instances in formsets when parent has 0 for primary
key (#21472).

Fixed a regression where custom querysets for foreign keys were overwritten
if ModelAdmin had ordering set (#21405).

Removed mention of a feature in the --locale/-l option of the
makemessages and compilemessages commands that never worked as
promised: Support of multiple locale names separated by commas. It’s still
possible to specify multiple locales in one run by using the option
multiple times (#21488, #17181).
